<p>A method and system for tank overfill prevention comprising the steps of supplying fluid to the interior of the tank by means of a dispenser, measuring the dispenser pressure Pd and flow rate Q, determining at equal time increments delta t a number of quantities representing tank pressures, another quantity representing the rate of increase of tank pressure with respect to time, comparing the quantity thus obtained with a present critical value, and shutting off the fluid supply, if this said quantity exceeds the said preset critical value and if the said flow rate Q is less than a preset critical value.</p> |
